How to use this tool
3 times a day is the default and means every 8 hours.
Use the hour and minute you plan to take the first dose.
All dose times for the 24-hour cycle are shown, wrapping past midnight.
Food timing and missed-dose rules in the leaflet override even spacing.
Formula & worked example
Medicine 3 times a day starting at 08:00 is taken at 08:00, 16:00 and 00:00, every 8 hours.
Limitations — read this before you rely on it
Scheduling arithmetic only. It does not set a dose, and food, sleep and missed-dose instructions in the prescription govern. This tool is for education only and is not medical advice. Talk to a clinician about any result that worries you, and never change treatment because of a calculator result.
Frequently asked questions
Three evenly spaced doses, every 8 hours, not just three doses while awake.
The tool wraps times past midnight, so a dose may fall at 00:00.
That depends on the medicine; the leaflet instruction overrides even spacing.
Missed-dose rules differ by drug, so follow the leaflet or ask a pharmacist; never double up unless told to.
Only with a prescribed dose and schedule; this tool only spaces the times.
